Palworld – Guide to Breeding for Both IVs and Passives

Definitive Datamined Guide to Breeding for Both IVs and Passives

This post is a compilation of datmining and empirical testing info which has gone under the radar for many. It gives the inheritance chances for both IVs and Passives.

Passives

There are two rolls for passives. An inheritance roll, and a mutation roll. If all four slots are filled from the inheritance roll, the mutation roll is skipped. If the parents have more passive skills than are inherited, they’re chosen randomly.

• Duplicate passive skills on both parents neither help nor harm inheritance chances
• It doesn’t matter which parent has which passive skill. A 2-2, 3-1, and 4-0 distribution all have the same odds

This table shows the odds for inheriting a given number of passives:

IV Inheritance Chances

IVs (“Innate Values”, a term borrowed from the pokeymon fandom), represent a Pal’s genetics, and determine the random variation in stats from pal to pal. There are three IVs, ATK, DEF, and HP. They are heritable, and increase the amount of stats you gain from level to level. A maximum IV will raise its corresponding stat gains at each level-up by 30% (for the most part. Legendary Alpha pals have much higher HP potentials) At level 1, this will be insignificant, but at level 50 the bonus will be quite substantial.

Austin John Gaming did a 100-sample test to determine inheritance chances for IVs, however he made a miscalculation and in his conclusions reported half of the actual inheritance chances. His actual data shows that each IV has the following odds of inheritance:

• 30% Father
• 30% Mother
• 40% Random mutation

This means that the odds of inheriting all three IVs from either parent is (60%)³ = 21.6%

Breeding for Both IVs and Passives

If you’re looking to breed pals for both passives and IVs, you should first try to get a pal with no passives, but max IVs (alpha pals tend to have above-average IVs, so look for high IVs from them). Failing that, you can settle for max IVs with no undesired passives. Breed pals with one or more perfect IVs together until all the IVs are perfect, and it has no passives, or no unwanted passives. This website can tell you what a pal’s IVs are, but you’ll have to level it up a little to tell for sure, due to rounding errors in the in-game stat screen.

Next, obtain a pair of pals with the four passives you want distributed between the two of them, and breed them with your perfect IV pal. Your goal should be to obtain a breeding pair with the four passives you’re looking for distributed between the two of them, no undesirable passives, and max IVs.

Note that when working toward this, partial successes can increase your odds. If you get a child with the passives you want, but only 2/3 IVs maxed, you can swap them in to increase your odds of getting all three IVs maxed.

Finally, breed your perfect IV parents together until you get perfect IVs and four passives. Once you’ve assembled the final breeding pair, the odds are:

• 21.6% to inherit all three IVs from either parent
• 10% to inherit all four passives

Total: 2.16%, or about 1/46
